Google Web Fonts project's goals are to create a directory of core web fonts for the world and to provide an API service so that anyone can bring quality typography to their webpages.

Using web fonts can be a great way to improve the look and feel of your website. Unfortunately, adding web fonts to your site adds extra overhead to your site and can often slow your page load times. If you've worked hard to ensure that your application has a fast load time, the last thing you want to do is slow it down with extra HTTP requests that carry unnecessary weight.
